“…On the contrary, the glasses in the Corrosion station 3, with a lower deposition rate of atmospheric chloride ions (Table 2), presented punctual attacks (pits). This latter pathology has been previously observed as result of accelerated tests in alteration chambers without the influence of marine aerosols [55] and they are the result of surface soiling because surface deposits retained water on the glass producing punctual attacks [10,47,55].…”

“…This damage can also accelerate the degradation reaction because pits can retain water favoring the formation of alteration layers around them (Figs. 3 a, b and c) [47], and the silica gel layers also retain water and leached ions, which can induce the basic mechanism of corrosion (Section 4.1) [42,49].…”

Urban and industrial atmospheres can produce several damages on glass façades and historical stained-glass windows; however, the effect of coastal atmosphere on them has been scarcely studied. This work presents the results of the exposure of soda-lime, potash-lime, and mixedalkali silicate glass to the coastal atmosphere in Cape Vilán (Galicia, Spain) at different distances to the coast (inland) during twelve months. Crystalline deposits were observed on all the samples, although their quantity depended on the meteorological conditions. The samples located nearest to the coast presented alteration layers, while those ones located farthest from the shore presented several isolated pits. Regarding the chemical composition, potashlime silicate glass, typical composition from medieval glass windows, was the most altered glass in contrast to soda-lime and mixed-alkali silicate glasses.

“…In addition, the surface composition (and structure) may be modified by specific protective treatments such as those used in dishwashers (with zinc and bismuth, or with polyethyleneimine), the efficacy of this surface modification being clearly demonstrated 67,68 . The chemical durability in atmosphere also depends on the environment: it has been demonstrated that the presence of deposited dust on the glass surface, such as wind-blown sand 69 , usually considered as inert, strongly decreases the atmospheric glass durability.…”

Glass alteration in atmospheric conditions: crossing perspectives from cultural heritage, glass industry, and nuclear waste management

et al. 2020

While glass alteration in liquid water has been widely studied for decades, glass alteration in unsaturated atmosphere (relative humidity, RH < 100%) has been far less examined. However, the understanding of the mechanisms involved in the reactions between glass and water in vapor state is fundamental to several fields such as glass industry, conservation of glasses of the cultural heritage and long-term assessment of nuclear waste glasses. This paper outlines the issues raised by the atmospheric alteration of glass in these fields and attempts to summarize the scientific approaches and findings of the three communities. This short review reveals that atmospheric alteration should not be confused with liquid alteration at high S/V (S = exposed surface of glass and V = volume of solution), because the kinetics and the nature of the alteration products are distinct. Notably, alkalies and non-bridging oxygens may be significantly retained in glass hydrated in unsaturated atmosphere, depending on the glass composition. Future lines of research are drawn to progress in the understanding of the specificities of atmospheric glass alteration.
